Anyone accused of a crime related to the death of another person could be in serious legal trouble in Canada. Charges ranging from murder to manslaughter to infanticide carry varying levels of moral blameworthiness and criminal punishment. If you or a family member is facing manslaughter charges, you’re in the right place. This guide will tell you everything you need to know; we’ll cover legal categories, mens rea, potential defences, and sentencing information, all in the context of Ontario.

Statutory Framework for Ontario Manslaughter Charges

First and foremost, it’s critical to understand the statutory framework in place concerning manslaughter, murder charges, and infanticide.

Under Section 222 of the Criminal Code, a person has committed homicide when they cause the death of another human being.

Subsections 2-6 of this same section break things down a bit further. They state that homicide may be considered culpable (legally liable) or non-culpable (not legally liable). The culpable forms of homicide are murder, manslaughter, and infanticide.

Manslaughter vs Murder (and Infanticide)

The main difference between murder, manslaughter, and infanticide lies in who is involved, the intent behind the homicide, and more. The table below will give you a quick look at the differences in the context of Canada (including Ontario):

Term Definition Legal Source
Murder When someone kills another person with intent and planning. Section 231 of the Criminal Code
Manslaughter When an individual commits homicide in the heat of passion caused by sudden provocation. Section 232 of the Criminal Code
Infanticide When a female causes the death of their newborn baby through a purposeful act or omission. To be classified as true infanticide, the mother must be in the birth recovery process or mentally affected by the consequences of childbirth or breastfeeding. Section 233 of the Criminal Code

Manslaughter in Ontario (and more generally, Canada) falls into a few key categories, including:

Voluntary Manslaughter

A crime is deemed voluntary manslaughter when someone dies due to another person’s attempt to harm, but not kill, them. A common situation where this may apply is in a brawl that went too far and resulted in one of the parties losing their life.

Involuntary Manslaughter

On the other hand, involuntary manslaughter is when someone unintentionally kills another without any intent due to:

  • Unlawful actions
  • Negligence
  • Recklessness

Involuntary manslaughter is broken down into two subtypes:

  • Unlawful-act (constructive) manslaughter: Death which is the result of an unlawful action (assault or battery, for instance) where the accused had no intent to kill. The referenced unlawful action should be dangerous in nature, meaning that it must carry a risk of substantial bodily harm.
  • Criminal negligence manslaughter: Death where the accused shows a deviation from a reasonable standard of care. In layman’s terms, criminal negligence causing death refers to situations where an alleged offender acted in a way that most would consider dangerous. Most of the time, this charge stems from grossly negligent or reckless conduct.

Key Canadian Cases Defining Manslaughter

A few leading Supreme Court of Canada cases help define these categories more precisely:

  • R v Creighton – Mens rea (1993): A man injected cocaine into a woman, and she died as a result. This case shed light on objective foreseeability in manslaughter in Canada. For unlawful-act manslaughter, the required mens rea (mental state) is that a reasonable person could foresee their actions causing serious or lasting bodily harm. The Court indicated that the accused individual doesn’t need to have foreseen death itself.
  • Smithers v R (1978): A man kicked someone else after a hockey game, and they subsequently choked and died. In establishing causation, the Crown has to show that the act was a contributing cause of death outside the de minimis range – meaning more than a trivial contribution.
  • R v Jobidon – Consent Defence (1991): A man was charged with manslaughter after a fist fight. This case zeroed in on the limits of consent as an assault defence. In a consensual fight, once serious or non-trivial bodily harm results, consent is vitiated (negated) and can no longer be used as a defence.

Speak with a defence lawyer for more information.

“Manslaughter cases in Ontario are among the most complex areas of criminal law. The difference between a conviction for murder and manslaughter often comes down to intent, foreseeability, and how the evidence is presented in court. Having skilled legal representation is critical to ensure that your rights are fully protected.” — Joel Prajs, Criminal Defence Lawyer at Vilkhov Law

Sentencing for Manslaughter in Ontario

Let’s take a look at the law surrounding a manslaughter sentence in Canada. Legal experts look to the Criminal Code for manslaughter in Canada, including Ontario. Section 236 states that the crime of manslaughter is an indictable offence with a maximum penalty of life in prison.

As for penalties for manslaughter with a firearm in Ontario, the mandatory minimum sits at 4 years in prison. If there is no firearm, there’s no mandatory minimum to observe. In these cases, the sentence will be determined based on several different factors:

  • The nature of the illegal act or negligence.
  • How much harm was inflicted.
  • The accused’s personal circumstances.

Sentences for aggravated manslaughter and domestic cases range from 7 to 12 years in Ontario.

Examples of aggravating circumstances include abuse of power, weapon use, extreme recklessness, and more. And mitigating factors may include lack of a criminal record, mental illness, and provocation.

Manslaughter Defences and Sentencing Mitigation

Those who have been accused of homicide aren’t without options. For instance, when provocation can be proven, lawyers may use a heat-of-passion manslaughter defence in an attempt to reduce a murder charge to manslaughter. Then there are contextual and factual defences: foreseeability (R v Creighton, 1993), the issue of consent (R v Jobidon, 1991), diminished responsibility, and more. Not only do these defences and mitigating factors affect a case’s outcome, but they also affect the resulting sentence.

Final Thoughts on Manslaughter Charges in Ontario

A manslaughter charge comes with numerous nuances that ultimately dictate how the case is treated in court and defended by lawyers. If you or someone you know is facing the GTA manslaughter charges, it’s critical to talk to a skilled Barrie, Mississauga, Brampton, or Newmarket criminal lawyer at Vilkhov Law. Considering the steep consequences of these charges, it only makes sense to partner with the best possible defence lawyer you can find.

I am an attorney for criminal law and administrative law in California. They previously represented a client of mine about 2 years ago in a serious criminal matter. Thanks to their excellent advocacy and hard work, the charges were withdrawn by the court due to no reasonable prospect of conviction. Their hard work helped bring about a just outcome and absolve my client of the charges.Recently this month, I (as well as my client’s separate firm) needed access to my client’s past criminal case materials for another administrative matter. Mr. Vilkhov and Mr. Slobodkin were extremely helpful and professional in providing the necessary documents and court transcripts. Their prompt assistance and continued support, even years after the case concluded, truly stood out. Mr. Vilkhov was very professional and courteous and his law clerk Daniel was incredibly helpful and friendly, especially toward my client. Daniel also assisted me with filling out the court transcript order form since I am not too familiar with the Canadian court process, titles, numbers or labels.Their professionalism, responsiveness, and dedication to their clients are commendable, even years after my client’s case was concluded. I highly recommend Igor Vilkhov and Daniel Slobodkin to anyone in need of skilled and trustworthy legal representation in criminal defense.Lucia GurzauLucia Gurzau ★★★★★ I had an outstanding experience working with Igor Vilkhov.
